Abstract: In an embodiment, apparatus having a touch-sensitive screen, a touch-sensor controller and a flexible printed circuit. Conductive electrodes are substantially aligned with one or more gaps between pixels of the two-dimensional array. First conductive electrodes form vertices within the one or more gaps between pixels of the two-dimensional array such that the vertices do not obscure in plan view. The touch-sensor controller is configured to detect and process the change in capacitance at one or more touch-sensor nodes to determine the presence and location of a touch-sensor input. One or more tracks of conductive material is electrically connected to the flexible printed circuit.

Abstract: A device and a touch sensor having a substrate and a plurality of columns of electrodes disposed on a side of the substrate.

The drive electrode of a particular interior column has a main electrode line that extends a length of the particular interior column. A first sense electrode and a second sense electrode of the sense electrodes of the particular interior column are located on opposite sides of the drive electrode.

Abstract: A capacitive touch sensor wherein the touch sensitive panel has drive electrodes arranged on the lower side of a substrate and sense electrodes arranged on the upper side. The drive electrodes are shaped and dimensioned to substantially entirely cover the touch sensitive area with individual drive electrodes being separated from each other by small gaps, the gaps being so small as to be practically invisible. The near blanket coverage by the drive electrodes also serves to screen out interference from noise sources below the drive electrode layer, such as drive signals for an underlying display, thereby suppressing noise pick-up by the sense electrodes that are positioned above the drive electrodes.
